1. What is Calcium Dosing?

Calcium dosing is essential for maintaining proper calcium levels in reef aquariums. Corals, clams, and other calcifying organisms require calcium to build their skeletons and maintain healthy growth.

2. How Does the Calculator Work?

The calculator uses the calcium dosing formula:

\[ Dosage (g) = (Target Ca - Current Ca) \times Volume (L) \times 0.02 \]

Where:

Explanation: This formula calculates the precise amount of calcium supplement needed to raise your aquarium's calcium level from current to target concentration.

3. Importance of Calcium in Reef Aquariums

Details: Proper calcium levels (380-450 ppm) are crucial for coral growth, skeletal development, and overall reef health. Maintaining stable calcium prevents stress and promotes vibrant coral colors.

4. Using the Calculator

Tips: Enter target calcium (typically 400-450 ppm), current measured calcium level, and total aquarium volume in liters. Always test water parameters before dosing and make adjustments gradually.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal calcium range for reef aquariums?
A: Most reef aquariums thrive with calcium levels between 380-450 ppm. SPS-dominated tanks often benefit from the higher end of this range.

Q2: How often should I test calcium levels?
A: Test weekly for established tanks, or more frequently when making dosing adjustments. Monitor consumption rates to establish proper dosing schedules.

Q3: Can I overdose calcium?
A: Yes, excessive calcium can precipitate with other elements and cause imbalances. Always dose gradually and test frequently during adjustments.

Q4: Should I dose all at once or split doses?
A: For large adjustments (>50 ppm), split the dose over several days to avoid shocking organisms and maintain stability.

Q5: What affects calcium consumption rates?
A: Coral load, growth rates, alkalinity levels, and water changes all impact calcium consumption. Heavy SPS tanks consume calcium faster than soft coral tanks.
